There is exif metadata in .arp file, which is saved with image. But when I look exif metadata by clicking right mouse “properties → detail”, there is no metadata.
Metadata saving mode and check marks are set correctly.
What app are you using to view the metadata? Windows Explorer?
I’m on Windows 11 but for example, this image (IMG_5372.CR3) was edited in ART 1.17.2. Both the raw file and the output TIFF have EXIF, at least (although there are fewer tags in the TIFF).:

C:\data\images\Our-photos\20221214_raingauge>exiv2 -P E .\converted\IMG_5372.tif | wc -l
33
And likewise if I select the TIFF in Windows Explorer, right click, select Properties and then the Detail tab, there’s metadata there. If I open the TIFF in ART, there’s metadata.
